To all whom it may concern:

Be it known that I,'GEoRoE E. EMERsoN,

a citizen of the 'United States, and a resident of-N'ewark, in thecounty of Essex and State of New Jersey, hawe invented certain newand'useful Improvements in Light and Sound DistributingApparatus, ofwhich the following is a specification.

This invention relates to lightand sound distributing apparatus.

The organization of the invention com; prises means for producing soundwaves, saidsound waves coacting with the-heat of light rays,'produced bythe appurtenances of the invention, and from-which results adistribution of the saidsound waves.-

The .invention assumes the form of apiece of artistic furniture, andspecifically comprises a sound prod'ucingapparatus coacting with theheatresulting from a source'oi light, preferably a lamp, the lamp generallysources of light may be used. The lamp'is positioned to coact with thesound waves produced by the apparatus without interfer'-' ing with thevibrations thereof. Some of the forms in which the invention may beembodied are shown and described in this application, although thedisposition of the elements shown, may be varied in numerous wayswithout departing from the invention;

The source of light or lamp of the invention is surrounded by an envelopof heated air, the hottest layer being adjacentto the lamp, and thetemperatures of the layers decreasing with their distance from the lamp.The velocity of sound increases with the temperature of the transmittingmedium,

the velocity increasing at about the rate of 23.9inches with one'degreeCentigrade. The end of the sound wave nearest to the lamp travels fasterthan the portion more distant from the lamp. The direction of advance ofthe sound wave before entering the un equally heated mass of airsurrounding the lamp is parallel to the axis of the lamp,

andvariably heated strata of air about, the lamp cause a turning of thesound wave, so.

thatthe direction of advance thereof is diverged from the axis of'thelamp, thereby producing a distributionof the sound waves. In the variousforms of the invention shown and described, in which the source ofillumination consists of a lamp 'within the sound duct or horn of theapparatus, the lamp 1S separated or stepped-01f from the latter, so.-that the advance of the sound translucent material that will reverberatefrom the efi'ects of the sound waves impingthereon, and thereby performthe functions of asound horn.

Referring to the accompanying drawings, Flgure 1 represents anelevationand partial axial section of one form of the invention, Fig.2.shows an enlarged fragmentary portion of Fig. 1, Fig. 3 is a top viewof Fig. 2 with some of the elementsomitted, Fig. 4

partial axial section ofa second modification 0f the invention, Fig, 7shows an elevation of: a third modification of the invention, Fig. 8represents a modification of Fig. 7 and .Figs. 9 and 10 show elevationsof: further modifications of the invention.

Referring particularly to Figs. 1 to4, a motor box is shown at 20 havingthe base frame 21, the roof plate 22, the side wall 23 carrying electricappurtenances to be de-- scribed, and the side wall 25 having formedtherein the large opening 26 with the door 27 The motor box in thisinstance contains the electric motor 30, although other styles of motorsmay be used. The motor 30 is belted'to the spindle 31 of the turntable32 carrying the disk record 33. A sound pro- 33. Upon the crown 36 ofthe sound complement is detachably supported'the hollow base 46 ofacombined lamp stand and sound duct 47 having extending from'its outersurface the flange 4:8.- .From the top of the stand 47 extend curvedbranch sound ducts 50. At the intersection of the ducts 50 is formed abell end 51 with a guide slot 52, and at the ends of the said ducts 50are formed bell ends 53 having guide. slots,

which latter bell ends and slots aresimilar to 51 and 52. The bell end51 carries a bell shaped globe 54, and the bell ends'53 carry similarbell shaped globes ,55. The globes 54 and 55 constitute sound horns forthe sound duct 47. The globes 54 and 55 may consist of any suitablematerial and may be of clear glass or of translucent and reverberatingmaterial.

In each of the bell shaped ends 51 and 53 there is provided a soundregulating device consisting of the disk shouldered at 61 and havingperforations 62, guideway 64 and axial opening 65. The disk 60 is heldin place in its bell end by means of the knees 66. A rotatable disk 67with perforations 68 and hollow hub 69 is located upon the disk 60,being guided by the shoulder 61. The perforations 68 are of equal areawith the perforations 62. Adjusting clips 70 have heels 71, that bear onthe outer c1rcumferential portion of the disk 60, and

their other ends bear on the disk 67. Adjusting screws 72 are inthreaded engagement with the disk 60 and enable the clips 70' to bearwith requisite pressure upon the disk 67, to produce suflicientfrictional resistance between the two. disks to hold the disk 67 inproper position, when variable sound ports are formed with theperforations 62 and 68. A regulating handle 73 with the knob 74 extendsfrom the disk 67 bears on the guideway 64 and extends through the guideslot 52. A conduit 75 is fastened to the hub 69 and supports theelectric lamp 76. The axial center of the lamp 76 coincides with theaxial center of the globe fastened to its accompanying bell end.Sufficient room is left between the outer surface of the lamp and theinner surface of its globe to permit the easy transmission of soundwaves from the ducts of the apparatus. A lamp shade 80 preferably oftranslucent reverberating material with a parabolic crown 81 is carriedon a supporting ring 82, which latter is carried by rods 83 extendingfrom a ring 84, the latter being preferably made in two halves, so thatit can be clam ed in place on the upper portion of the" net-47 andsupported on the flange 48 of the latter. A pair of mainline wires 90,91 for electric current extend to the plug 92supported in the wall 23 ofthe motor box 20. A wire 93 extends from the plug 92 to a binding post96 on the electric motor 30, and a wire 95 extends from a second bindingpost 94 on the motor to a controlling switch 97 in the said wall 23. Thewire 93 has extending therefrom the wire 98 and a wire 99 leading fromthe plug 92 is connected with a second controlling switch 100. A wire102 connects the switch 97 with the plug 92 and a wire 103 connects saidplug and switch 100. The wires 98 and 99 are wound together into a coil105. The coil 105 extends through the conduit 47 of the lamp and thecentral bell shaped end 51, and branch coils 106, 107 extend through theducts 50 to conduct the requisite electric energy to the lamps 76 of thebell ends.

The operation of the invention is evident from the description of theparts and it wili sutlice to say .that by means of the controllingswitch 97, the motor 30 can be either started or stopped, therebycontrolling the rotations of the turn-table 32 and the production of.sound from the disk record 33, with the cotiperation'of the speaker 41and horn 40. The controlling switch 100 enables the operator toenergize'the lamps 76 and shut olf the current therefrom. The soundapparatus and the lamps may be either made to perform their functionsseparately or simultaneously. When the sound waves leave the horn 40they travel up the duct 47 and pass through the globes 54, 55 whichlatter constitute secondary horns. After the sound waves leave the globe54 they strike the parabolic crown 81 of the lamp shade '80,.reverberate the latter and are deflected end of the duct 110 extend, inthis instance,

three curved bran'ch sound ducts 114, which each have formed therewithbell ends 115, that contain the disks 60 and 67, the lamps 76 and theirappurtenances as already described. The ell ends 115 have formedtherewith the combined lamp globes and sound horns'11-6 preferably oftranslucent and reverberating material and that have extending therefromthe pins or projections 117. A lamp shade 120 preferably of translucentand reverberating material is formed with openings 121 extending up fromthe lower edge 122 theerof. The. shade bears upon the horns 116, theopenings 121 registering therewith, and the pins 117 enter smallopenings formed in the lamp shade In Fig. 6 is represented the motor box20 with its appurtenances and the sound producing compartment with thewall 35 and crown 36. Both the motor box and sound producing compartmentare similar to those already described. A lamp stand 125 is fastened tothe crown 36 and has-fastened in the axial center thereof the main soundduct 126. A pipe fitting'127 with the horizontal pipe 128 is fastened tothe sound duct 126, and the pipe 128 has flexibly jointed thereto thearm 129 with the speaker 41. The latter coacts with the disk record 33as shown. From the upper end of the main sound duct 126 extend theflexible branch sound ducts 130, that gradually increase in diameterfrom their inner to their outer ends. The ducts 130 have each connectedthereto the bell end 131, which is similar and contains appurtenancessimilar to the bell ends 51 and53 already described. To the bell endstranslucent material that will reverberate' with sound waves.

In'Fig. 7 the motor box 20, and a sound producing compartment having thewall and crown 36, with their contents are preferably similar to theform shown in Fig. 6. The stand in this instance is indicated at 140being appropriately,ornamented. The stand contains a sound duct similarto 126, which latter has extending therefrom the'elbow 141 to which isattached the hollow goose neck 142, the latter increasing in diameterfrom its lower to its upper end. A bell end 143 is attached to the upperend of .the goose neck and is similar and has appurtenancessimilar tothe bell ends 131. A globe 144 is provided with a lamp having the bulb145 and which in addition to its function as a distributer of lightperforms the function of asound horn. By reason of the form of the globe144 and form ofthe bulb 145, there is .produced an annular space betweenthe bulb and globe which, in a plane taken through the longitudinal axisof said elements resembles the form of asound horn as indicated at 146.

In- Fig. 8 the motor box 20, .and a sound producing compartment havingthe wall 35 and crown 36, with their appurtenances are preferablysimilar to'those shown in Fig. 6.

' The lamp stand is indicated at 150, which is capped by a hollow balland socket joint 151. The stand preferably contains a sound duct similarto 126, which. leads to the hollow balland socket joint. An elbow 152extends from the ball and socket joint 151 and connects with the hollowgoose neck 153. A bell end 154 is attached to the upper end of the gooseneck and is similarandhas appurtenanc'es similar to the bell end 131. Aglobe and sound horn 155 is provided for a lamp eontained'therein, whichalso performs the function ofa sound horn. By means of the belland'socket joint the globe and sound horn 155 can be placed in anyangular position to direct the sound and light waves in any direction.In Fig. 9 the motor box 20, l with a sound producing compartment hav ing.the wall--35 and crown 36 with their contents are preferably'similar tothe form shown in Fig. 6. The lamp stand which constitutes the soundduct is indicated at 160. A bell end 161 with appurtenances similar tothose of the bell'end 53 and its appurtenances is formed at the top endof the stand 160. A sound horn 162 extends from the bell end 161. Aplurality of inverted lamps 163 are supported on the ends of the goosenecks 164, that extend from the top end of the stand 160 and which maybe flexible. A lamp shade 165 of translucent reverberating material andpreferably parabolic at its crown is supported on the ring 1.66, and thelatter iscarried on the rods 167 extending from the ring 168, detachablyconnected to the stand 160.
